In the Analyzed Liquid Treatment Facility of Japan Nuclear Fuel Co., Ltd. (JNFL) MOX Fuel Fabrication Plant (J-MOX), the interfere by salts with the analysis of gross alpha activity concentration analysis will be caused during the treatment process. Therefore, JNFL devised the desalting method using a solid-phase extraction chromatography. Japan Atomic Energy Agency carried out the experimental study to confirm the validity of this desalting method for the treatment liquid based on the contract with JNFL. This study consists of three experiments as follows: Step 1 - Selection of an optical solid-phase extraction agent, Step 2 - Evaluation of variation optical solid-phase extraction agent, and Step 3 - Application of the imitation liquid waste. The result of Step 1 determined the solid-phase extraction agent (InertSep ME-2) and the optimum condition (aspiration method by manifold (about 5-10 mL/min), 3M nitric acid as eluent, pH: 5, and no adjustment of ionic valence). Then, the result of Step 2 and 3 made sure the validation of this method by obtaining over 70% recovery for the imitation liquid waste sample of the Analyzed Liquid Treatment Facility of J-MOX.

The combination of ADAAM and Tetraethyldiglycolamide (TEDGA) as a masking agent shows selectivity for Am(III) over Cm(III) in highly acidic media with separation factors up to 41.

In the field of uranium ore refining and spent fuel reprocessing, a lot of extractants capable of recovering actinides have been innovated, and some of which have been developed in actual industrial scale processes. Extractability against trivalent actinides on each extractants were evaluated in this report. And as for the compounds which showed excellent extractability for Americium, their extraction characteristics for trivalent actinides, such as extraction behavior, mechanism, ligand structure and conformation of complexes, were evaluated, and filed as data-base. Based on these works, some of extractant were newly identified as candidate to apply Americium recovering. The most appropriate compounds for trivalent actinide separation can be generally found in the neutral bidentate organic compound groups: Especially, some derivatives belongs to Diphosphineoxide, Carbamoyl-methylphosphine oxide and Propandiamide were superior to give sufficiently excellent property even in higher nitric acid(1
3M) solutions. Innovative research towards developping new extractants and extraction system seems to be directed to ; (1)investigate new types of extractant sustained by a different kind of complexing mechanism, (2)evaluate synergistic effect of adducts, diluents even including conventional extractants.
